Flattening Test

One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot.

Flange Test

One flange test shall be made on specimens from each end of one finished tube, not the one used for the flattening test, from each lot.

Reverse-Bend Test

One reverse-bend test shall be made on a specimen from each 1500 ft [450 m] of finished tubing.

Hydrostatic or Nondestructive Electric Test

Each tube shall be subjected to either the hydrostatic or the nondestructive electric test. The purchaser may specify which test is to be used.

Grain Size

Grain size determinations on grades TP309H, TP309HCb, TP310H and TP310HCb shall be made on the same number of tubes as prescribed for the flattening test.

Markings

In addition to the marking prescribed in Specification A 1016/A 1016M, the marking for Grades TP304H, TP309H, TP309HCb, TP310H, TP310HCb, TP316H, TP321H, TP347H, and TP348H shall also include the heat number and the heat-treatment lot identification.

 Note:

  • Mill test certificates will be issued according to EN10204.3.
  • All tubes shall be supplied as per applicable ASTM A249 /A249M Specification.
